Limestone Minerals Education Coalition

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite.

What is difference between cement and lime? Quora

A cement is a binder, a substance used in construction that sets and hardens and can bind other materials together. The most important types of cement are used as a component in the production of mortar in masonry, and of concrete, which is a combination of cement and an aggregate to form a strong building material.

Cement Producers Are Developing a Plan to Reduce CO2

Portland cement is produced in large part with limestone, a type of rock that's composed mainly of a chemical compound called calcium carbonate. To produce the sticky, binding cement, the limestone must be heated at high temperatures—around 1,500 C, according to civil and environmental engineering expert Claire White of Princeton University.
